In order to prepare monoclonal antibody to σ A protein of avian reovirus(ARV)and es-tablish a sandwich ELISA method for the detection of ARV pathogens.In this study,the σ A pro-tein of ARV was expressed as antigen by prokaryotic expression and used to immunize BALB/c mice.Then,stable hybridoma cell lines were screened,and monoclonal antibodies were prepared.A sandwich ELISA detection method based on monoclonal antibody of σA protein was established,and the sensitivity,specificity,repeatability,and accuracy were tested.The results showed that the recombinant plasmid pET-32a-σA was successfully constructed and well expressed in Escherichia coli.After immunizing mice,two hybridoma cell lines 6B3 and 8E11,which could secrete mono-clonal antibodies stably,were successfully prepared.Both monoclonal antibodies could react with natural ARV.One of the monoclonal antibodies secreted by 6B3 was selected as the capture anti-body and the ARV-positive chicken polyclonal antibody was used as the detection antibody.A sand-wich ELISA method was established to detect ARV by optimizing the reaction conditions.The specific test showed that the method only detected ARV pathogens and no other common chicken viral pathogens were detected.The detection limit was 7.72 X 102 EID50/mL of ARV antigen.The coefficient of variation of the intra-and inter-assay tests were less than 5.0％and the reproducibili-ty was good.Thirty samples were tested simultaneously by σA-sandwich ELISA and PCR,and the results were consistent with each other.In conclusion,a sandwich ELISA method based on the monoclonal antibody of σA protein was successfully established for the identification and detection of ARV,which provided a technical means for the accurate and rapid detection of ARV.

Objective:To analyze the early warning value of laboratory examination on admission of patients with hemorrhagic fever with renal syndrome to critically ill patients.Meetods:In this study, a retrospective case-control study was used to analyze the clinical data and laboratory examination results of patients with hemorrhagic fever with renal syndrome admitted to the emergency department of Tangdu Hospital of Air Force Medical University from January 2021 to January 2022. According to the patient's laboratory indexes and clinical symptoms, the patients were divided into mild, moderate, severe and critical groups. The general data of the two groups were compared, and the independent risk factors of critically ill patients were screened by multi-factor logistic regression analysis, the predictive model of severe HFRS patients was constructed, and the ROC curve was drawn. .Results:Of the 164 patients with HFRS, 50 were in the severe group and 114 in the mild group. The serum levels of WBC, AST, ALT, Cr, BUN, DD and PCT in the severe group were higher than those in the mild group, while the levels of PLT, ALB and PTA in the severe group were lower than those in the mild group. Multiple logistic regression analysis showed that WBC, PLT and PCT were independent influencing factors for the progression of critically ill patients. The predictive model of severe HFRS was established as follows: logit (P) = -0.321 + 0.040 WBC (×10 9/L) -0.045 PLT (×10 9/L) + 0.086 PCT(ng/mL). The early warning ef?cacy of WBC, PLT, And PCT for severe HFRS was further analyzed. The area under the ROC curve (area under curve, AUC) was 0.779, 0.842, 0.862, and the optimal threshold was 10.435×109/L, 41.5 ×109/Land 2.97 ng/mL, respectively. The AUC of joint detection is 0.900, the sensitivity is 88.0%, and the speci?city is 82.5%, which is better than that of a single laboratory. . Conclusions:HFRS laboratory indexes have certain clinical signi?cance for the identi?cation of critically ill patients, in which serum WBC, PLT and PCT indexes are the risk factors of severe HFRS, which provides a theoretical basis for clinical diagnosis, treatment and prognosis of severe HFRS patients.

OBJECTIVE To observe the efficacy of cetrorelix combined with aspirin in preventing early-onset ovarian hyperstimulation syndrome （OHSS）. METHODS A retrospective analysis was conducted on clinical data from 38 early-onset OHSS patients， who received treatment in our hospital from January 1st to July 1st， 2022. These patients were divided into intervention group （19 cases） and control group （19 cases） according to the therapy regimen. On the first day after oocyte retrieval surgery， the control group was given aspirin enteric-coated tablets 100 mg orally until menstruation began. The intervention group was given cetrorelix for injection 0.25 mg subcutaneously， for consecutive 3 days+aspirin enteric-coated tablets （same usage and dosage as the control group）. The first luteal phase， the degree of OHSS， and the ovarian volume， ascites volume， serum estradiol （E2）， white blood cell count （WBC）， hematocrit （HCT）， neutrophil ratio （NEUT%）， D-dimer （DD）， prothrombin time （PT）， fibrinogen （Fib） after oocyte retrieval surgery were observed and measured in 2 groups. RESULTS The first luteal phase was significantly shorter， and the proportions of median and severe OHSS cases were significantly lower in the intervention group compared to the control group （P＜0.05 or P＜0.01）. After oocyte retrieval surgery， the intervention group showed significantly lower ovarian volume， ascites volume， serum E2， WBC， NEUT%， HCT， DD and Fib compared to the control group， but PT of intervention group was signiticantly higher than that of control group （P＜0.05）. CONCLUSIONS Cetrorelix combined with aspirin is more effective in preventing early-onset OHSS than aspirin alone.
